4 ; This used to cause a crash. A standard load is converted to a pre-increment
5 ; load. Later the pre-increment load is combined with a subsequent SRL to
6 ; produce a smaller load. This transform invalidly created a standard load
7 ; and propagated the produced value into uses of both produced values of the
8 ; pre-increment load. The result was a crash when attempting to process an
9 ; add with a token-chain operand.
